PROBLEM TO BE SOLVED: To provide a less-complicated, low-cost anti-noise system for influencing exhaust gas noise propagated in a multi-flow exhaust system.SOLUTION: An anti-noise system comprises: a controller 80; and at least one actuator. The at least one actuator is arranged in a sound generator 20, 21, connected to the controller 80 for receiving a control signal, and adapted to generate sound in the sound generator 20, 21. The sound generator 20, 21 can be simultaneously connected to at least two exhaust paths 60 and 61 in a multi-flow exhaust system of a vehicle. The controller 80 is configured to generate the control signal for controlling the at least one actuator arranged in the sound generator 20, 21 to cancel at least partially, preferably completely the internal sound of the at least two exhaust paths 60 and 61 in the multi-flow exhaust system of the vehicle. |
